BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 595,057, dated December 7, 1897.

Application filed March 17, 1897. Serial No. 627,983. (No model.)

To aZZ zvhmn it may concern:

Be it known that I, FREDERICK A. GLINES, a citizen of the United States, residing at Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful BicycIeBelI, of which the following is a full, clear, and exact description.

The object of this invention is the construction of a bell for bicyles which shall be automatieally rung by the resistance of the air caused by the vehicles progress and which may be thrown out of gear and made silent whenever desired.

In the drawings forming part of this specification, Figure 1 is an elevation, partly in section, of my bell and actuating mechanism. Fig. 2 is a cross-section of the same through so so in Fig. 1. Fig. 3 is a detail sectional view drawn on a larger scale. Fig. 4c is a detail top View of a part thereof, and Fig. 5 is a longitudinal section of a modification.

The main portion of my invention coinprises the wind-wheel m, the bell a, hammer h, the supporting-stud c, and the clamp for attaching the whole to the handle-bar or steering-head of a bicycle. Said clamp consists of the two parts a 6, adapted to clasp the handle-bar or similar part and clamped together by the bolts 6 The clamp-section e is provided with the boss d, into which is rigidly fastened, either by screw-threads or brazing, &c., the tubular stud c. Movable upon said stud is the sleeve b, carrying the bell or gong a and provided with the finger-piece b for retracting the same against the pressure of the coiled spring f. For holding said sleeve in this position of retraction the sleeve is given the lock-slot 5 into which extends the pin 23 from the stud c. Said slot being of the approximately 5.. shape as shown in Fig. 4, a combined pull and rotative pressure applied to the finger-piece Z) insures the entrance of the pin b into the locking portion of said slot and the consequent retention of the sleeve in its desired position of retraction. The object in thus reciprocating the sleeve 1), and consequently the gong mounted thereon, is to render the latter mute or to put it into sonorous vibration. The manner in which this is effected is as follows:

Within the stud c is the slender shaft g, carrying the wind-wheel m. Rigidly connected with said shaft and wheel is the arm h, having the striking disk or hammer 72. in its bifurcated extremity. The axial pin 71, of this disk is loosely held in t-he'slotted bearings 7L3 in said arm and thereby permitted a limited radial play. As said hammer rotates with the wind-wheel 'm it comes in contact with the rib a within the gong a and causes the same to sound. By drawing back the gong, however, its edge'is brought out of the range of the hammer and the latter rotates without possibility of striking the rib a. Hence no matter how rapidly the wind-wheel now revolves the bell is utterly mute.

The wheel on is usually constructed from thin sheet metal and is retained in place upon the shaft g by means of the shoulder and nut 71;. The boss h is for the purpose of counterweighting the hammer and arm 77. h.

The shaft g is retained in the stud c by having its outer portion larger in diameter than the remainder and attaching to the end of the stud a collars, abutting against the shoulder thus formed. The inner end of the shaft is made conical, as 9 and bears against the recessed plug d.

In Fig. 5 I show my preferred arrangement of the shaft. Here there is no collar 0, but the shaft is held in place by the conical head g being of larger diameter than the shaft and bearing between the end of the stud c and the bottom of the socket (1 in which said stud is secured. r

In using this bicycle-bell it is fastened upon the handle-bar or other convenient part of the frame, with the finger-piece Z) uppermost and the rib a consequently at the lower side of the gong. If the rider wishes the bell to sound, he gives the finger-piece a side hit, the locking-slot b is released from the pin b the sleeve and "on slide forward the 7 b b J rib a comes into the path of the hammer, and the speed of the bicycle through the air-pressure upon the wind-wheel produces the desired result. The rider can now speed upon his way without further attention to the bell, which will continue its resonant vibrations so long as the bicycle is in motion. If now the rider comes to an unobstructed stretch of road and no longer wishes his bell to ring, he simply gives a pull to the finger-piece I) and locks the gong out of contact with the ham mer. The wind-wheel, however, continues its whirling, attracting the attention of passers-by to the novel and attractive sight, and ready at an instants notice to again resume its audible duty. The advantages in thus permitting the wind-wheel constant rotation and puttin git into and out of gear by removal of the gong from the path of the actuating devices are, first, that no shock is given to the mechanism by an instantaneous stopping of the wheels motion and no strain is given by thus holding it motionless; further, the Wheel being in rapid rotation the gong is loudly rung upon the instant of throwing the latter into position. Were the wheel required to work up to the required speed from a state of rest, there would be a more or less dangerous delay in setting the gong into vibration.

What I claim as my invention, and desire to secure by Letters Patent, is as follows, to Wit:

1. The combination of the Wind-wheel and hammer, the stud revolubly supporting the same and adapted to be secured to a vehicle, and the gong longitudinally movable upon said stud and thereby removed from or put into contact with said hammer, substantially as and for the purpose specified.

-2. The combination of the wind-wheel and hammer, the stud revolubly supporting said wheel and hammer, the sleeve movable upon said stud, the gong mounted on said sleeve and having rib normally contacting with said hammer, a spring for retaining said gong in said normal position, and a lock for fastening the said sleeve and gong away from the normal position, substantially as and for the purpose specified.

3. The combination of the wind-wheel and hammer, the stud revolubly supporting said wheel and hammer, the sleeve movable upon said stud and having finger-piece,b, and locking-slot, 5 a pin, 6 projecting from said stud into said slot, the gong mounted on said sleeve and the spring for normally retaining said gong and hammer in retroactin g position, substantially as and for the purpose specified.

4. In a bicycle-bell, the combination of the clamp, e, having socket, 01 the stud, 0, se-
